Is it normal for new engine oil to be red?

[OClara]

Some engine oils are light red when first added, as this is their original color from the factory, which is a normal phenomenon. Engine oil, also known as motor lubricant, serves multiple functions for the engine, including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Below are the key functions of engine oil: 1. Friction Reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and pistons, minimizing gas leakage and preventing the entry of external contaminants. 3. Rust Prevention: The lubricant adheres to part surfaces, protecting them from contact with water, air, acidic substances, and harmful gases. 4. Shock Absorption: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the piston, piston rings, connecting rod, and crankshaft bearings, the lubricant transmitted through the bearings helps cushion the impact load. 5. Cleaning: High-quality engine oil can carry away carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, cleaning the working surfaces of parts via the flow of the lubricant.
